The first was obvious – the tennis champion’s first child was named after her Reddit co-founder dad Alexis Ohanian, in a twist on the trend of naming children after their parents.

However, we’re only just finding out the second meaning a month on, despite it being right in front of us the whole time.

Williams, who has confessed she’s “having a hard time” posting about anything other than her daughter on social media, sent out a Tweet on Thursday telling her followers that Alexis Olympia’s name contained a touching nod to Australia.

The 36-year-old was in the very early stages of pregnancy when she won her 23rd grand slam at the Australian Open in January.

And for this reason, Williams wanted her daughter’s initials to reflect that she had a baby on board.

Fun fact my daughters initials are AO as in the Aussie open she won with me @AustralianOpen
